SAW-MILL FEED MECHANISM.

To all whom iii 777,601] concern.-

Be it knownthatl, GEORGE FRANKLIN LIDY, of Waynesborough, in the countyof ed to be adjusted diametrically across the face of a frictional diskfor varying the speed and of the disk.

the roller whenever the friction between the disk and roller is notsuitably gaged to overcome the weight of thecarriage. This happensbecause the weight of thecarriageholds the roller stationary, while thefrictional contact of the disk grinds the periphery of the roller,causing a flat surface thereon. Such a construction is all the moreobjectionable, because the roller'is ordinarily made of paper or otheryielding substance, because of its frictional quality, and theflatsurfaces are rapidly formed in such a roller, rendering it irregularand unsteady in its action.

To overcome this objection I locate the paper roller on the saw-arbor,in order that its continuous rotation with the arbor shall cause itsperiphery to be worn uniformly when the friction is not great enough todrive the disk; and thus prevent any part of the periphery from beingflattened.

framework, B the saw, 0 the arbor carrying .the saw, and D the pulleyfor driving the arbor.

1 On the arbor is feathered the sleeve E, carry- .ingthe paper roller F,andthis sleeveis connect- ,ed by a finger, G, with a slotted arm, H,which is rigidly attached to a sh aft, I, having alever, J, for rockingthe shaft and arm, to cause the sleeve to slide on the arbor. The leverJ is connected to the shaft I by means of a squared opening, K, in itslower end, which is fitted over a squared block, L, on the end of theshaft, and a transverse bolt, M, passing through the lever and saidblock. With this construction the lever may be oscillated in twodirections at right angles to each other. The lower end of the lever isfitted in a concentric groove, N in a swinging bearing, 0, pivoted at Pto the frame A. This bearing carries one end of a shaft, Q, on the otherend of which is rigidly secured the frictional disk B. This shaft Q isalso provided with a bearing, S, to which is feathered a bevel-pinion,T, which is also feathered on the shaft Q, and geared with a largebevel-gear, U, mounted on the shaft V. The shaft V is provided'with apinion, W, for driving the carriage Y. "With this construction the shaftQ is adapted to receive a slight longitudinal movement by oscillatinglever J on pivot M, for throwing the disk into and out of contact withroller F.

As already implied, by rocking the shaft I with lever J, the roller Fmay be adjusted nearer to or farther from the center of disk R, to varythe speed of the carriage Y, and if shifted from one side of the centerof the disk to the other side the direction of the motion of the in theswinging bearing and carrying the frictional disk, the pinion featheredon said shaft, and the carriage-driving shaft and the gear mountedthereon, substantially as shown and described.
